Abstract

The study aimed to determine the effect of the use of feed concentrates containing Moringa leaf flour on protein consumption, protein digestibility and rumen ammonia concentration. Data were analyzed using a randomized block design (RBD) with 4 treatments and 3 replications, and continued with the Duncan test. The treatments in this study include: K1: Concentrate without the use of Moringa leaf flour; Concentrate with the addition of 10% Moringa leaf flour; K3: Concentrate with the use of Moringa leaf flour 20%; and K4: Concentrate with the use of 30% Moringa leaf flour. The variables determined were Rough Protein Consumption and Digestion and rumen NH3 Concentration. The results showed that protein (g / tail / day) consumption and crude protein digestibility (%) were highest in the treatment of K4: 36.37 and 72.01, then followed by K3: 35.81 da. 71.93; K2: 35.06 and 69.85 and K1: 31.99 and 59.91. The highest rumen NH3 (mM) concentration is also occupied by K4: 19.77 followed; K3: 18.24; K2: 16.48 and K1: 11.16. The results of statistical analysis showed that the treatment had no significant effect (p> 0.05) on consumption and had a significant effect (p<0.05) on the digestibility coefficient of crude protein and rumen NH3. It was concluded that the use of Moringa leaf flour as a constituent component to the level of 30% can be used for animal feed to increase consumption and nutrient digestibility of livestock as well as the provision of rumen NH3.

Abstract

The objective of study to determine the chemical meat composition of kacang male goat fed ration with different energy sources. The livestock used were 12 male goats with an average initial body weight of 11.77 kg, ranging in age from 6 to 12 months according to dental estimates. The design used was Randomized Block Design (RBD) with 4 treatments and 3 replications. The each treatment was T0 = 80% Natural Grass + 20% Leucaena leucocephala ; T1 = 50% natural grass + 20% Leucaena leucocephala + 30% milled corn; T2 = 50% natural grass + 20% Leucaena leucocephala + 30% rice bran and T3 = 50% natural grass + 20% Leucaena leucocephala + 30% cassava. Variables observed in this study include meat protein content, meat fat, water content and collagen. The results of study showed that the meat protein content of male kacang goat received T1 treatment was higher (P <0.05) than the animals treatments of T0; while the animals that were treated with T0, T2 and T3 were relatively the same protein content. Conversely, the variables of meat fat, collagen and meat water content were relatively the same between treatments. It can be concluded that the use of milled corn as an energy source in male kacang goat can increase the meat protein content. However, the fat content, collagen, and water content of the meat have not shown significant differences between treatments.
